INVESTIGATION OF THE CAUSE OF AN EXCESSIVE DUD RATE OF CARTRIDGE, 40MM, HE: M406, LOT MA-10-3
Abstract
A 576-round firing test was conducted to determine the cause of the high dud rate of Cartridge, 40mm, HE: M406 (Lot MA-10-63) with Fuze, M551 (Lot MHR-20-3). Twenty-four dud projectiles were recovered and disassembled. Inspection of the fuzes revealed eight unarmed, seven partially armed, two with defective firing pins, and seven with indentations in their detonators. The overall dud rate of the 576 rounds was 4.34%. There is no significant dif ference between the dud rate of the test sample and the acceptance criteria.
